The peak on my SVT-4PRO randomly cuts on and off causing it mute on and off however when I use a mute/graphic equalizer foot pedal it works just fine. There is one problem with the pedal. Instead of holding the foot switch down to mute my bass or hold down the other switch on the pedal to engage the EQ, it does the opposite. I have to press and hold one pedal to unmute and press and hold the other pedal to disengage the EQ. It could be the type of pedal that I am using which is the one shown below. Can anyone help me?
